Study Guide — K.OA.A.4
Make 10 partners
Ten-frames help children see partners that make 10 (e.g. 7 and 3).
What this standard means
- Find the partner to make 10 from any number 1–9
- Use ten-frames to show the missing part
- Record with equation (e.g. 7 + 3 = 10)
- Recall common make-10 pairs with practice

How to use the 20 practice sets
| Sets | When to use | | --- | --- | | 1–5 | Intro — explore together, short written items | | 6–10 | Core skills — diagrams and written practice | | 11–15 | Mixed review — explain thinking | | 16–20 | Stretch — word problems and mastery tasks |
Pacing: 10–15 minutes per session.

Common mistakes
- Counting on fingers without using 10 structure
- Confusing which number is the partner
- Adding to get 10 when subtracting is clearer
Review and practice tests
1. Start Review 1/10 when sets 1–3 feel comfortable. 2. Move up one review level with little help. 3. Use Practice Test 4/10–6/10 for mid-standard checks. 4. Practice Test 10/10 is the mastery bar for K.OA.A.4.
